Abstract

Die Erfindung betrifft einen Gewindestecker an einem langgestreckten Körper für eine Gewindeverbindung mit einer Gewindebuchse, wobei der Gewindestecker ein konisches Außengewinde aufweist, bei dem ein Abschnitt einer Flanke des Außengewindes als Abschnitt einer Funktion darstellbar ist, die eine Krümmung aufweist, wobei der Abschnitt der Funktion über eine Höhe des mindestens 0,3-fachen der Gewindehöhe einen Winkel zu einer Verbindungslinie benachbarter Gewindegründe bzw. Gewindespitzen aufweist, der größer als 45° ist.
